NASA's Mars Spacecraft Capture Images of Comet 3I/ATLAShttps://www.spacedaily.com/reports/NASAs_Mars_Spacecraft_Capture_Images_of_Comet_3I_ATLAS_999.htmlPasadena CA (JPL) Nov 21, 2025 Two orbiters and a rover captured images of the interstellar object - from the closest location any of the agency's spacecraft may get - that could reveal new details. At the start of October, three of NASA's Mars spacecraft had front row seats to view 3I/ATLAS, only the third interstellar object so far discovered in our solar system. The Mars Reconnaissance Orbiter (MRO) snapped a close-u

Second CHAPEA Crew Begins Extended Mars Habitat Mission at NASA Johnsonhttps://www.marsdaily.com/reports/Second_CHAPEA_Crew_Begins_Extended_Mars_Habitat_Mission_at_NASA_Johnson_999.htmlLos Angeles CA (SPX) Nov 26, 2025 NASA's second CHAPEA (Crew Health and Performance Exploration Analog) mission is underway with four volunteers - Ross Elder, Ellen Ellis, Matthew Montgomery, and James Spicer - beginning a 378-day simulated Mars stay inside a 1,700-square-foot 3D-printed habitat at Johnson Space Center in Houston. The mission started October 19, 2025, and will conclude on October 31, 2026. The crew will re

ClipE96: We Left the Clipboard Unguarded for 40 Yearshttps://news.ycombinator.com/item?id=46051434In 1984, Apple shipped copy and paste. It was a miracle of usability—and architecturally broken from day one.Press Ctrl+C and the entire payload—bytes, formatting, metadata, embedded objects—dumps into a system buffer that any application can read. No auth. No logging. No revocation.The clipboard is a broadcast channel disguised as a convenience.The catastrophe: The clipboard is now the #1 data exfiltration vector in enterprise. 77% of knowledge workers paste corporate data into AI tools. Every paste bypasses your CASB, EDR, SIEM, and DLP. Your security stack guards the front door while users walk data out the side.The waste: 40 billion copy operations/day × ~100KB average = 4 exabytes of daily churn. RAM pressure, cloud sync, VM duplication—all unnecessary. Annualized: 83B kWh, 33M tons CO₂, $10B in energy costs. We're burning a small nation's power grid because nobody questioned whether copying a sentence needed to ship a document.The semantic lie: Copy and cut were always opposites,

Show HN: Memory System Hitting 80.1% Accuracy on LoCoMo (Built in 4.5 Months)https://github.com/vac-architector/VAC-Memory-SystemI’ve been working on an independent memory-retrieval architecture for agent systems. I don’t have a CS background — previously worked climbing cell towers and doing handyman jobs — but I spent the last 4.5 months building a hybrid memory system from scratch.The system combines FAISS, BM25, and a symbolic ranking layer (MCA). Answers are generated with GPT-4o-mini at temperature 0. The focus is determinism, transparency, and reproducibility rather than model size.On the official LoCoMo benchmark (1,540 questions), the system reaches 80.1% average accuracy. To my knowledge, that’s above the publicly reported results for existing agent-memory stacks using small models.Latency is ~2.5 seconds, and cost is ~$0.10 per 1M tokens. Memory is fully isolated and local, which makes it usable for offline or enterprise applications.Repository (code + full reproducible benchmarking): https://github.com/vac-architector/VAC-Memory-SystemHappy to answer technical questions, discuss the architecture, or

Platinum Crystals Mapped as They Develop Inside Liquid Metalhttps://www.spacedaily.com/reports/Platinum_Crystals_Mapped_as_They_Develop_Inside_Liquid_Metal_999.htmlSydney, Australia (SPX) Nov 25, 2025 Scientists at the University of Sydney have demonstrated the growth of platinum crystals in liquid metal by applying advanced X-ray tomography techniques. This research offers fresh understanding of the crystal formation process within dense, opaque materials. The team built an electrode using metallic crystals capable of efficiently producing hydrogen from water. These crystals, grown in

Show HN: Open-Source Visual Wiki Your Coding Agent Writes for Youhttps://www.npmjs.com/package/daviaHi HN,We’re Ruben, Afnan, and Theo. A couple of days ago we released the early repo for Davia and were surprised by how much feedback came in right away. We decided to turn it into a full open-source package you can run locally.Davia is designed for coding agents to generate an editable internal wiki for your project. It focuses on producing high-level internal documentation: the kind you often need to share with non-technical teammates or engineers onboarding onto a codebase. Writing this kind of documentation takes forever, diagrams are often missing, and most tools don’t let you edit everything locally or integrate smoothly with your workflow.Davia is fully open source. It produces an editable workspace: – Text lives in a Notion-like editor – Diagrams live on editable whiteboards – Everything runs locally and can be modified either in your IDE or in the workspaceOne thing people found especially interesting is that you can delegate the documentation to your IDE’s AI agent.

Show HN: Ilseon, a Minimalist Focus Filterhttps://github.com/cladam/ilseonI’m excited to share a new productivity app I recently released on the Play Store. It was born out of pure necessity to solve a problem I am constantly faced with: cognitive overload and task paralysis.Since traditional to-do apps only added to the mental noise, I eventually built a small tool for myself called Ilseon. I needed something that would actually reduce cognitive load.I have added some features that helps me in my daily chaos:Context filtering: I work better when I only see what belongs to the role I’m currently in (Work, Family, Health, etc.). Switching context hides everything else, which stops me from bouncing between unrelated tasks or getting overwhelmed by a big master list.Time blocks with a big visible countdown: This externalises time for me in a way alarms or calendars never did. It gives me one clear block to focus on, and the timer helps with time blindness without being stressful. Still figuring out if adding alarms is a good idea or not..A quick reflection loop
